Pheidole dentata
Toothed Big-headed Ant
Pheidole dentata is a North American ant species notable for its well-studied behavioral development and neural plasticity. Workers exhibit age-related repertoire expansion, progressively taking on new tasks throughout their lives rather than following a rigid sequence. Research has demonstrated that this behavioral development correlates with neurochemical changes, including increased serotonin and dopamine levels, and cephalic muscle maturation. The species serves as a model organism for studying division of labor, brain miniaturization, and behavioral robustness to sensory injury.
